Title: Fuel control apparatus
Inventor: SIMOMURA SETSUHIRO
IPC: G01F1/698
Filed: 1987-03-25
Granted: 1990-03-09
Abstract: A sensor connected by hot-wire bridge type provides a signal to the electronic control unit with further sensing devices which include a throttle value sensor, a crank angle sensor, and a cooling water temperature sensor.  A fuel control or injector valve is provided for each cylinder.  The ECU determines and controls the amount of the fuel injected from the injector at a pre-determined air-fuel ratio with respect to the quantity of the air sucked into each cylinder. The fuel quantity determination is based on signals from engine operating parameter sensors and effected by controlling the duration of pulses applied to the injector valves.

Abstract: a number of active zones(8-7, 8-8, 8-9, 8-10, 8-11) for each memory cell formed in a common substrate using the same diffusion process for providing diffusion zones of 2 adjacent cells, separated by a channel zone; word lines(8-5, 8-15) extending at an angle to the channel zones, and perpendicularly to evenly spaced bit lines(8-3); capacitors extending longitudinally between the adjacent bit lines(8-3) and sidewords between 2 adjacent word lines(8-5, 8-15); and an insulation layer having contact holes(8-2, 8-4) for connecting the first diffusion zones to the capacitors and the contact holes(8-2, 8-4) for connecting the second diffusion zones to the bit lines(8-3). The memory layout can arrange the memory cells to be highly integrated.

Abstract: 본발명은 온디멘드형의 잉크제트프린터헤드 및 그 제조방법에 관한 것으로, 잉크제트프린터헤드는 판두께 방향으로 분극된 판형상의 압전부재와, 비도전성 및 비전왜곡성으로서 상기 압전부재의 강성보다 낮은 강성의 재료에 의해서 형성되어 상기 압전부재의 접합된 기판과, 상기 압전부재의 표면에서 이 압전부재와 상기 기판과의 접합면을 초과하는 깊이로 형성된 일단에 잉크토출구를 가지고 잉크공급부에 접속되는 복수의 압력실과, 이들의 압력실의 양측에 배치되어 상기 압전부재와 상기 기판에 형성된 복수의 지주와, 상기 압력실의 상기 기판측의 일면과 양 내측면과의 전면에 접합된 복수의 전극과, 상기 압전부재에 표면접합된 천판으로 구성되어 있으며, 그 제조방법은 판두께 방향으로 분극된 판형상의 압전부재와 비도전성 및 비전왜곡성으로서 상기 압전부재의 강성보다 낮은 강성의 재료에 의해서 형성된 기판을 접합하고, 상기 압전부재의 표면으로부터 상기 기판의 내부에 도달하는 가늘고 긴 복수개의 홈을 연삭가공에 의해서 형성하며, 상기 기판의 상기 홈의 표면에 이 기판의 내부조직을 노출시켜서, 상기 홈의 전내면에 전극을 무전해 도금에 의해서 형성하고, 상기 압전부재의 표면에 천판을 접합함으로서 상기 각홈의 개구면을 폐색하여 압력실을 형성하며, 이들의 압력실에 잉크토출구를 형성하도록 하는 것이다.
